MACHINE FOR PRODUCING COMMERCIAL SOUND RECORDS.

Original application filed September 12, 1921, Serial No. 500,012. Divided and this application filed May To all w out it may conoc'rn lie it known that I, Howann L. PAGE, a citizen of the United States, residing at Chicago. in the county of Cook and State 5 of Illinois, have invented a certain new and useful Improvement in Machines for Producing (,ommercial Sound Records, of which the following is a specification.

The invention is of value to the user of a machine in the nature of a phonograph recorder and reproducer for commercially recording sound waves synchronously with the taking of the motion picture of the person. animal or other object producing the sound to be recorded and for converting the rccord so produced into a phonograph record of commercial quality which will reproduce the sound previously recorded synchronously with the exhibition of the picture '0 of the objects which were photographed as the original sound record was made. Such a. machine is shown in my original application, Serial No. 500,012, filed September 12, 1921, of which this is a division.

In general terms. the objects of the invention are to produce a machine for use in making 'a master record and commercial records from the photographic sound record originally made in such a machine as the machine mentioned in the first paragraph.

The invention consists in amachine capable of attaining the foregoing objects, which can be easily and cheaply made, which is satisfactory in use and is not readily liable to get out of order.

The invention further consists in many features and details of construction which will be hereafter more fully set forth in the specifications and claims.

Figure 1 is a perspective view of a machine illustrating this invention in its preferred form used in making a master film from an original negative.

Figure 2 shows the same machine used in making a commercial record from the master record or film.

For the purpose of insuring identity of this divisional application with the original application, said figures are merely reproductions of Figures 17 and 20 of said original application with only the figure numbers changed, the letters of reference on the figures being otherwise those of the original application.

adjustable trough edges 192 and 194 between which the film passes, a heated material tank 190 warmed by the electric coil 198 delivering record material through a spout 200 onto film upon the table 190; a scraper 202 adjustable vertically on a rod 204: by means of a set screw 207. The table may, if desired, be provided with a cooling coil 200, to keep the parts at proper temperature.

In the operation of this machine the film body 178 carrying what is in the case here illustrated a soft spongy gelatinized member 182 is passed over the table 190 under the spout 200 and thence between the members 192 and 194. Tank 196 is filled with a material which when heated can flow down onto the film 178 on table 190 and fill no the space at the side of gelatinized portion 182 without injuring the gelatine. It should also be a material which when cooled does not materially shrink and which is hard enough to stand the forming of a final record from it when it is again run through the machine of Figure 1 or one similar thereto as shown in Figure 2 for this purpose. Such a material is found to be gutta percha and wax and asphaltum in approximately equal parts. The asphaltum makes it set when cold. the gutta percha makes it fiexi- Me and the wax gives it body and holds the other parts together. As this material passes down the spout 200 onto the table it fills in the space on the film 178 not occupied by gelatin member 182 and forms the matrix 210 and adheres firmly to the film 178. As the product of the machine of Figure 1 is wound onto the reel 188, the. material forming the matrix 210 becomes cooled and congeals to a flexible body of substantial thickness, while the swelled gelatine 182 loses by evaporation the water which it held in suspension and dries to a film or coating the thickness of which is very small, as fully described in said original application, leaving the unshrinkable member matrix 210 as the outstanding feature of the film,

This record just described is kept as the master record from which reproducing records for use in a reproducing machine may be made when and as desired When it is desired to make such a reproducing record, this master record is run through the machine of Figure 2 which difiers only from that of Figure 1 in that additional film carrying rolls 212 and 214; are provided above the machine, said rolls being adapted to have gummed paper 216 pass from roll 212 to roll 214 over a suitable moistening roll 218 and thence under a pressing roller 220 located immediately above the table 190 where it can force the paper 216 into contact with record member 222 formed on the table by feeding a mixture of liquid celluloid from tank 196 down onto the moving film 178 and between record 210 and the guide 194:. In other respects, the machine operates just as the machine of Figure 1 does, the operator if he likes manipulating a; rolling pin 226 to be sure that the celluloid aterial 222 accurately fits into place in register with the record 210. When the machine carries the gummed paper record 216 down into contact with the moving film 178 carrying the celluloid record 222, the paper adheres to this celluloid 222 and forms the finished record which is seen in Figure 2 passing upward from roller 220 to roller 214.

This finished record has a very hard and strong record portion 222 of celluloid and a very light and inexpensive carrier portion 216 of paper. It can be readily replaced without much expense by running the same celluloid or other celluloid through the machine of-Figure 2 in conjunction with the record 178-210.

In the whole productive operation, the only point requiring excessively competent high skilled labor is the making of the one master record while the gelatin portion 182 is spongy; at all other points, everything is hard and accurate and it is not easy to have trouble.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a machine of the class described, a table, means for moving a strip of record bearing film over the table, means at each side of the film adapted to retain plastic material on the film as it passes over the table, means supplying plastic material onto the passing film between the retaining devices, means above the surface of the film for shaping the upper surface of plastic material 0n the film between the retaining devices, means for moving another strip of supporting or backing material between two polnts away from the table over a point in close proximity to the top of the table, and means holding the portion of backing material which is close to the table in contact with. the plastic material passing over the table.
